Regional Models
*Notes: The first column is the 4-letter abbreviation code used in
naming datafiles. The MM5 model was initially tested with two sets of
parameters, one from PNNL and one from ISU. The MM5 model is being
run by the ISU modeling group, and the results are therefore
referred to as MM5I, but it is being run using the PNNL parameters
because they produced better results. If data generated using the ISU
parameters becomes available, it will be designated MAIP (MM5 -
Alternate ISU Parameters) to try and minimize confusion.

*Note: NCEP is not a GCM, but a reanalysis, a restrospective model
of the atmosphere based on observed data. NARCCAP uses NCEP-DOE
Reanalysis 2, sometimes referred to as "NCEP-2".

Timeslice Experiments: The two timeslice experiments are
run using the GFDL AM2.1 and the NCAR CAM3 models. These correspond
to the GFDL and CCSM drivers, respectively. Each RCM is therefore
paired with one of the GCMs that has a corresponding timeslice
experiment.
